摘要
A theoretical model for the oxidation of blends of kerosene, biofuels, and synthetic fuels is proposed in this work, with the biofuel portion being represented by methyl tridecanoate (MTD), a methyl ester with chemical formula C(14)H(28)O(2), and the synthetic fraction being represented by heptane. The model is based on previous work performed by the authors on the development of a reaction mechanism including kerosene and methyl butanoate. (MB), the Aviation Fuel Reaction Mechanism version 2.0 (AFRM v2.0). AFRM v2.0 has been updated through a multi-parameter optimization, including the addition of the reactions for the breakdown of the C-14 methyl ester and a set of reactions for the oxidation of heptane. The final scheme consists of the surrogate kerosene components n-decane and toluene, a surrogate fatty acid methyl ester (FAME) (methyl tridecanoate), and a surrogate of the synthetic paraffinic portion, heptane. The scheme also includes NO(x), SO(x), and polycyclic aromatic hydrocarbon (PAH) chemistry. Perfectly stirred reactor simulations were compared to experimental results by Dagaut et al. for the oxidation of biokerosene and pure heptane in a jet-stirred reactor at different fuel/O(2) equivalence ratios. Because of the lack of available experimental work on blends, burner-stabilized flame validation has been carried out for pure kerosene only.
